6. Maintenance

Brelko belt scrapers are designed to operate with minimum maintenance. However, to maintain superior performance some service is required. When the scraper is installed a regular maintenance program should be set up. This program will ensure that the scraper operates at optimal efficiency and problems can be identified and fixed before the scraper stops working. All safety procedures for inspection of equipment (stationary or operating) must be observed. The E901 Head Pulley Scraper operates at the discharge end of the conveyor and is in direct contact with the moving belt. Only visual observations can be made while the belt is running. Service tasks can be done only with the conveyor stopped and by observing the correct lockout/tag-out procedures.

6.1. New Installation

After the new scraper has run for a few days a visual inspection should be made to ensure the scraper is performing properly. Make adjustments as needed.

6.2. Routine Visual Inspection (every 2~4 weeks)

• A visual inspection of the scraper and belt can determine:

• If the mounts are adjusted at the correct pressure for optimal cleaning

• If the belt looks clean or if there are areas that are dirty

• If the blade is worn out and needs to be replaced

• If there is damage to the blade or other scraper components

• If fugitive material is built up on the scraper or in the transfer area

• If there is cover damage to the belt

• If there is vibration or bouncing of the scraper on the belt

• If a snub pulley is used, a check should be made for material build-up on the pulley

• If any of the above conditions exist, a decision should be made on when the conveyor can be stopped for scraper maintenance.

6.3. Routine Physical Inspection (every 6~8 weeks)

When the conveyor is not in operation and properly locked and tagged out a physical inspection of the scraper to perform the following tasks:

• Clean material build-up off of the scraper blade and pole.

• Closely inspect the blade for wear and any damage. Replace if needed.

• Check blade for proper installation and condition. Replace if needed.

• Ensure full blade to belt contact.

• Inspect the scraper pole for damage.

• Inspect all fasteners for tightness and wear. Tighten or replace as needed.

• Replace any worn or damaged components.

• Check the pressure of the scraper blade on the belt. Adjust the pressure if necessary, refer to scraper model installation guide.

When maintenance tasks are completed, test run the conveyor to ensure the scraper is performing properly.

INSTALLATION GUIDE - REF. DRW. No.: E905-003

1. Refer to the Assembly Instructions, Parts List and Parts list drawing to confirm that all the necessary parts have been supplied and that the scraper is correctly assembled.

2. Remove mounting brackets (7) from nearside bearing assembly (9) and farside bearing assembly (8).3. Referring to the installation data sheet and dimensions given in the dimension table determine the scraper work zone and select the

optimum position for the scraper.4. After establishing the optimum position for the scraper on the head pulley, mark and cut out the near and farside chute openings.

The farside opening need only accommodate scraper adjustment. • Note 1: - Shield the conveyor belt and head pulley to prevent burning during cutting and welding activities.• Note 2: - The mounting brackets (7) may be omitted and the bearing plates bolted directly to the chute sides. Separate chute

access doors may then be required for inspection and maintenance access. Please consult a Brelko representative for this installation option.

5. With reference to the installation data sheet select the most convenient location for the mounting brackets (7).• Note: - Mounting brackets (7) can be welded or bolted to the chute sides.

6. Tack weld the near and farside mounting brackets (7) to the chute sides or bolt to structure.7. Remove one or both carrier shaft (1) end caps and install scraper through nearside chute opening.8. Position carrier (1) centrally with reference to belt edges and head pulley and attach the nearside bearing assembly (9) and farside

bearing assembly (8) to the mounting brackets (7).9. Using nearside bearing assembly (9) and farside bearing assembly (8) as reference determine exact carrier (1) length, mark off;

remove carrier (1) and nearside bearing assembly (9) and farside bearing assembly (8).10. Carefully cut carrier shaft (1) to required length and de-burr shaft ends, reposition carrier shaft (1) centrally with reference to belt

edges and head pulley.11. Fit farside bearing bush (8a) over carrier shaft (1) end, and insert carrier shaft (1) end into farside bearing assembly (8). Tighten bolts

and nuts, finger tight only as further adjustment of the scraper will be required.12. Fit nearside bearing bush (9a) over carrier shaft (1) end, and locate nearside bearing assembly (9) as shown. Tighten bolts and nuts,

finger tight only as further adjustment of the scraper will be required.13. Complete welding of near and farside mounting brackets (7) or ensure all mounting brackets (7) nuts and bolts are firmly fastened.14. Locate tension unit (6) and insert holding bolt into matching holes between the nearside bearing assembly (9). Tighten holding bolt

and nut, finger tight only as further adjustment of the scraper will be required.15. With reference to the dimension data sheet move scraper into the correct scraping position. Tighten bolts and nuts; do not over

tighten nuts and bolts as further adjustment of the scraper might be required.16. Using large tool, turn tension unit to bias scraper against head pulley and insert holding bolt. The tensioner only needs to be rotated

until the first set of holding bolt holes between nearside bearing assemblies (9) align. 17. Firmly tighten all nuts and bolts.18. Start the conveyor and check if all blades are in full contact with the belt surface. If further adjustment is required stop the conveyor

and adjust the scraper until the next set of holding bolt holes between nearside bearing assemblies (9) align or until optimum cleaning is achieved.

7. Procedure for Replacing/Repairing Scrapers

Repair/replace Belt Scraper components when, general maintenance tasks are preformed scraper damage due to accelerated blade wear, scraper damage due to blocked chutes, clip joints/emergency belt repairs etc.

7.1. Request permit to work from an authorised person, who will isolate and lock out the belt.

7.2. Open access door, if provided, and clear loose items about the spindle before commencing with work.

7.3. Loosen the locknuts and then lower/raise the scrapers, as necessary.

7.4. If replacing scrapers, insert balance pipe – which must be longer than the carrier shaft – into the one end of the shaft.

7.5. Loosen the shaft and turn it 180 degrees, that is, scraper tips pointing downward.

7.6. Remove one spindle on the intended exit end.

7.7. Slide out the scraper assembly from the intended exit end of the pipe.

7.8. Service the scraper on the platform.

7.9. Blade replacement:

Refer to Brelko installation instructions for belt scraper model in use.

Brelko nylon torsion holders have been designed to break out of the torsion holder support v-track to protect the scraper, scraper mounting components, conveyor belt and conveyor belt equipment against damage due to emergency clip joints, loose/damaged splicing, belt protrusions, chute blockages etc. If torsion holders damaged occur follow the steps below to replace individual or all of the torsion holders:

a. Remove and clean the damaged scraper to assess the amount of damage to the scraper, the scraper torsion holders and scraper components.

b. If the scraper has been working for more than 4 weeks and/or there has been significant blade wear remove and replace all the torsion holders and blades and replace with new kits, this will eliminate belt damage due to uneven scraper torsion holder and blades.

c. If the scraper has been working for 1~2 weeks replace only damaged torsion holders and blades, however assess the damage and ensure the remaining torsion holders will not cause any damage to the conveyor belt.

7.10. Scraper Adjustment:

Refer to Brelko installation instructions for belt scraper model in use.

a. Reposition using the balance pipe.

b. Obtain sanction for test, or permission to adjust for performance evaluation.

c. Tighten all nuts and ensure that belt cleaning or scraper performance is acceptable.

d. Clear up any loose items which resulted from your work.

!!!WARNING!!!

General Safety ProceduresBelt conveyors and their transfer points can be dangerous. By their very nature, they feature many “pinch” points and speeding objects. They apply large amounts of mechanical energy to what is basically a loaded rubber band. Operations and maintenance personnel must always be aware of the power of a conveyor, and they must maintain a healthy respect for its potential to injure or kill an untrained or unwary individual.

General Safety GuidelinesThere are certain safety procedures that should be observed regardless of the design of the conveyor or the circumstances of operation.

They include:

1. Lock out/tag out all energy sources to conveyor belt, conveyor accessories, and associated process equipment before beginning any work-whether it is construction, installation, maintenance, or inspection in the area. Use a lock with one key for each piece of equipment. Only the person doing the work should hold the key to the lock.

2. Employees should be properly trained on the material handling System (including emergency warning signals and emergency stop controls) before they are allowed to work in the area or attempt to install any Brelko® equipment or system.

3. Employees and visitors should learn and observe all applicable company, local, state, and federal safety rules. It is recommended that a formal testing program covering the safety rules be conducted annually.

4. The recommended operating speed and capacity for the conveyor and chute should not be exceeded. If assistance for product selection is required, please contact your Brelko® representative.

5. All tools and work materials should be removed from the belt and chute before restarting a conveyor. A safety “walk around” is recommended prior to conveyor operation, making sure that all nuts and bolts are tightened on all Brelko® equipment or systems installed. Also ensuring that all other items adjusted during installation are tightened, safety guards replaced etc...

6. All emergency controls should be close to the system, easy to access, and free of debris and obstructions.7. A hard hat, safety glasses, and steel-toe shoes should be worn when in the area of the conveyor. Loose or bulky clothing should not

be allowed.8. Never poke, prod, or reach into a material handling system while it is in operation, to clean or remove foreign objects from the

Brelko® equipment or systems installed.The above guidelines are not intended to replace the safety guidelines of the industrial area, and must be used in conjunction with the industrial area’s safety regulations and those supplied by the manufactures of the specific systems.
